FORMALDEHYDE AND TRACER GAS TRANSFER BETWEEN AIR STREAMS IN ENTHALPY-TYPE AIR-TO-AIR HEAT EXCHANGERS.

Author(s) : FISK W. J.

Summary

THE PAPER DESCRIBES AN EXPERIMENTAL STUDY IN WHICH THE FORMALDEHYDE, TRACER GAS, AND WATER VAPOUR TRANSFER RATES IN TWO ENTHALPY EXCHANGERS WERE MEASURED. THE FIRST EXCHANGER USES A CROSSFLOW CORE FABRICATED FROM A TREATED PAPER AND THE CORE OF THE SECOND IS A ROTATING HEAT WHEEL COATED WITH LITHIUM CHLORIDE. TO REDUCE THE TRANSFER OF GASES BY AIR LEAKAGE, EACH CORE WAS INSTALLED IN A SPECIALLYFABRICATED CASE. FORMALDEHYDE TRANSFER BETWEEN AIRSTREAMS BY PROCESSES OTHER THAN AIR LEAKAGE DOES NOT SERIOUSLY COMPROMISE THE PERFORMANCE OF THESE EXCHANGERS. THEORETICAL CALCULATIONS INDICATE, HOWEVER, THAT THE TRANSFER OF WATER VAPOUR CAN SIGNIFICANTLY DIMINISH THEIR ABILITY TO LOWER INDOOR FORMALDEHYDE CONCENTRATIONS.
